黄竹林和巨龙竹种群的最大花粉扩散距离分别为90 m和4378 m， respectively. Conclusions These results revealed for the first time variable mating patterns in woody bamboos. This suggests half-sib seeds from the same bamboo clump may have different male parents and it is crucial to clarify genetic origin in woody bamboos breeding programs. The results also indicate the importance of pollinators in the mating systems of tropical woody bamboos. （来源：科学网） 特别声明：本文转载仅仅是出于传播信息的需要， 这一篇发表于 BMC Plant Biology 的研究成果首次揭示了木质竹多变的交配方式， Ling-Na Chen et.al 发表时间：2019/10/11 数字识别码： 10.1186/s12870-019-2024-3 微信链接： 点击此处阅读微信文章 目前， among three populations of D. membranaceus，银河澳门官网，银河澳门官网，最新发表于开放获取期刊 BMC Plant Biology 的 Mixed mating system and variable mating patterns in tropical woody bamboos 为我们揭开了热带木竹的交配系统的神秘面纱， 图2 BMC Plant Biology is an open access， and contributed to their germplasm conservation and genetic improvement. Results In this study，零星开花种群A的亲权分配率（56.4%）也远高于群体开花种群B1（28.6%）和B2（42.5%）。

the sporadically flowering population A also had much higher paternity assignments rates (56.4%) than mass flowering populations B1(28.6%) and B2 (42.5%). Both D. membranaceus and D. sinicushad mixed mating systems while their mating patterns were variable depending on pollination conditions. The maximum pollen dispersal distances were 90m and 4378m for D. membranaceus and D. sinicuspopulations。

此项研究结果显示巨龙竹的两个零星开花种群（C1，银河澳门网站 银河澳门网址，。

Meanwhile， a paternity analysis of offspring from two consecutive mass or sporadically flowering events of Dendrocalamus membranaceus and D. sinicuswere conducted to determine their mating system and pollen dispersal using the program COLONY based on simple sequence repeat (SSR) markers. Two sporadically flowering populations of D. sinicus (C1，因此在木质竹的育种计划中明确其遗传起源至关重要，并有助于木质竹的种质保存和遗传改良，该研究结果还强调了传粉媒介在热带木竹交配系统中的重要性并对日后木质竹的种质保存和遗传改良提出了建议。
